Carbonic Acid. Was I believe first introduced into practice by Dr Dobson and since used with much advantage by Drs Dawson & Thompson he first took the hint from observing that urinary calculi when immersed into malt liquors were dissolved by it. Percival & Falconer now understanding the fact under took a series of experiments to prove whether the fix’d air was the solvent power and they succeeded completely. The Waters of Pyrmont & Spa possess the solvent power and the urine becomes so impregnated that it also has the power of dissolving calculi. Of the use of carbonic acid in calculi I know nothing from experience, tho in gravel or affections of the kidneys I have used it in the shape of Seltzer water with great advantage, and when that cannot be procured as is often the case, I have substituted the saline effervessing draught; in the exhibition of which my practice has been to give the substances separate thereby producing the chemical action in the stomach:

Soda. This has also been recommended as a solvent for the calculi, the form of exhibitting the medicine is to expose the soda to heat to drive off the water of chrystalization, the following is the formula.
